  However, in the movable body feeding structure of the conventional example, it is necessary to attach the first extra length absorption guide case 100 to the vehicle body side and the second extra length absorption guide case 101 to the sunroof side. There was a problem that the structure was also enlarged.

  Further, unlike the conventional example, a structure using a general-purpose electric wire without an elastic member is conceivable, but the structure is further complicated.

  Therefore, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a power feeding structure for a movable body that can be easily mounted and can be configured compactly.

The present invention includes a rail member fixed to a fixed portion, a slider that moves along the rail member, and a movable body supported by the slider, and is provided from one of the fixed portion and the movable body to the other. In the power feeding structure for a movable body that performs power feeding, the wire includes one end connected to the fixed portion side and the other end connected to the movable body side, and a surplus length absorption mechanism that winds up the surplus length portion of the wire, The surplus length absorbing mechanism is movably disposed along the rail member, and the surplus length absorbing mechanism includes a case and a rotating body housed in the case, and the rotating body is A rotating guide circumferential wall that is rotatably guided by the inner circumferential wall of the case, and an electric wire winding portion connected to the rotating guide circumferential wall, and the electric wire winding portion is the electric wire on the movable body side. And the wire on the fixed part side An urging means configured to urge the rotating body in the winding direction of the electric wire on the movable body side and the electric wire on the fixed portion side is arranged in the inner peripheral space of the rotating guide circumferential wall. This is a power feeding structure for a movable body.

  According to the present invention, when the movable body moves in a direction away from the surplus length absorbing mechanism, the rotating body rotates against the urging force of the urging means, and is wound around the wire winding portion. The extra length absorption mechanism moves along the rail member toward the movable body side while pulling out both the electric wire on the movable body side and the electric wire on the fixed portion side, so that the movable body approaches the extra length absorption mechanism. When moved, the rotating body is rotated by the urging force of the urging means, and the extra length absorbing mechanism is wound around the electric wire winding part while winding the electric wire on the movable body side and the electric wire on the fixed part side together. It moves along the rail member in a direction to move away from the movable body side, and the extra length is absorbed.

  The surplus length absorbing mechanism only needs to be attached to the rail member on which the slider moves, and it is not necessary to separately install a rail member for the surplus length absorbing mechanism, so that the attachment is simple. The surplus length absorbing mechanism is provided with a rotating body that winds up the electric wire and an urging means that urges the rotating body, both of which are arranged around the center of rotation, so that the structure is simple. As described above, it is possible to provide a power feeding structure for a movable body that is easy to mount and can be configured compactly.

A cam pin 23 a of the rear slider 23 is inserted into each elongated cam hole 25 b of each middle slider 25. The pair of middle sliders 25 moves integrally with the pair of front sliders 21 in the vehicle front-rear direction FR, and moves with respect to the pair of rear sliders 23 according to the position of the cam pin 23a in the cam hole 25b. It moves in the front-rear direction FR and the vehicle vertical direction TB. With such a slider mechanism, the sunroof 30 closes the opening 3 as shown in FIG. 3A and closes the front of the opening 3 as shown in FIG. The position can be changed between a tilt-up position where the rear is opened and an open position where the opening 3 is opened as shown in FIG.

  As shown in FIG. 1, the sunroof 30 is attached to a pair of middle sliders 25. The sunroof 30 has a laminated panel body (in particular, no reference numeral) in which a transparent glass body and a light control panel are laminated at least. The light control panel is in an opaque state when no voltage is applied, and the transparency is varied according to the applied voltage level when a voltage is applied. Power is supplied to the light control panel from the vehicle body 1 side. This power supply structure will be described below.

  Each drive belt 40 is made of synthetic resin. Each drive belt 40 is long and has a vertically long cross section. On one surface of each drive belt 40, a tooth portion 40a is provided continuously in the longitudinal direction. Each drive belt 40 is disposed in the belt routing path 16 of the front frame 15 and the belt guide path 13 of the pair of rail members 11. Each drive belt 40 is a belt cover 46 in the area of the belt routing path 16 of the front frame 15 and a belt surrounding wall (in particular, no reference numeral) in the area of the belt guide path 13 of the rail member 11. It is covered so as not to easily buckle (bend deformation). As a result, the pair of drive belts 40 moves only along a predetermined locus even when the sunroof 30 is pushed backward from the front of the vehicle.

  One end side of the pair of drive belts 40 is fixed to the pair of rear sliders 23 (one drive belt 40 is fixed to one rear slider 23 and the other drive belt 40 is fixed to the other rear slider 23). The other end side is not fixed to any member. In other words, it is a free end.

  The deflector 50 includes a deflector body 51 and a pair of swing arms 52 that are rotatably supported at both left and right ends of the deflector body 51. The deflector body 51 is disposed at the front end of the opening 3 of the ceiling panel 2 over the entire region of the opening 3 in the vehicle body width direction. The deflector body 51 is formed in an arc shape on the front end side. This prevents the strong wind from the outside from entering the vehicle compartment directly from the opening 3 when the opening 3 is opened.

  The pair of swing arms 52 are rotatably supported by the pair of rail members 11. The deflector body 51 is moved to a standby position (a position shown in FIGS. 3A and 3B) below the opening 3 of the ceiling panel 2 and the ceiling panel 2 from the opening 3 by the movement of the pair of swing arms 52. The position can be changed between the wind-avoiding positions protruding upward (positions shown in FIG. 3C), and is urged toward the wind-avoiding positions by the spring force of the torsion spring 53. The deflector body 51 is located on the slide locus of the front slider 21. When the front slider 21 is in the closed position in FIG. 3A and the tilt-up position in FIG. 3B, the pair of swing arms 52 is in the front slider 21. In response to the pressing force from the torsion spring 53, the torsion spring 53 is positioned at the standby position against the spring force. When the front slider 21 is in the open position of FIG. 3C, the deflector body 51 is positioned at the wind avoidance position by the spring force of the torsion spring 53 without the pair of swing arms 52 receiving the pressing force from the front slider 21. .

  The water receiving member 60 is disposed across the entire region of the opening 3 in the vehicle width direction on the rear end side of the opening 3. The water receiving member 60 includes a sliding portion (not shown) that is slidably supported by the pair of rail members 11, a water receiving body 62 that is supported by the sliding portion and has a water receiving groove (not shown), It has a pair of arm parts 63 fixed to both ends of the water receiving body 62 in the vehicle width direction. In a water receiving groove (not shown) of the water receiving main body 62, a drain port 62a (shown in FIG. 1) is formed at a position directly above the drain channel 14 of the pair of rail members 11. The tips of the pair of arm portions 63 are rotatably supported by the middle slider 25. The water receiving member 60 moves following the movement of the middle slider 25 in the vehicle longitudinal direction FR and the vertical movement of the rear end of the middle slider 25.

  The water receiving body 62 of the water receiving member 60 is located at the rear end position of the opening 3 when the sunroof 30 is in the closed position in FIG. 3A, and the water falling from the gap between the sunroof 30 and the ceiling panel 2. receive. The water receiver main body 62 is located at the rear end position of the opening 3 when the sunroof 30 is tilted up in FIG. The water receiver main body 62 is located at a retracted position inside the ceiling panel 2 when the sunroof 30 is at the open position in FIG. Water or the like received by the water receiver main body 62 falls from the drain port (not shown) to the drain channel 14 of the rail member 11 and flows through the drain channel 14 of the rail member 11 to the front end or the rear end thereof. , (Not shown) and drained to the outside by a drain hose (not shown).

  Next, the fixing structure of the drive belt 40 and the rear slider 23 will be described. As shown in detail in FIGS. 4 and 5, the rear slider 23 includes a resin block 26 and an insulating metal bracket 27 fitted to the resin block 26. The location of the resin block 26 is disposed in the slide guide path 12. The resin block 26 is provided with one fitting protrusion 26a, and the metal bracket 27 is provided with two fitting protrusions 27a. The two fitting protrusions 27 a of the metal bracket 27 are disposed at both side positions in the vehicle front-rear direction FR of the fitting protrusion 26 a of the resin block 26. On one end side of the drive belt 40, a fitting hole 44 is opened at a position corresponding to each fitting projection 26a, 27a. By fitting the fitting protrusions 26 a and 27 a of the resin block 26 and the metal bracket 27 into the fitting holes 44 of the driving belt 40, the driving belt 40 and the rear slider 23 are connected.

  Next, a power feeding structure from the vehicle body 1 side to the sunroof 30 will be described. As shown in FIGS. 1 and 8, the movable body power supply structure is arranged in the middle of the flat wire W routed along the rail member 11 and the route of the flat wire W. And a surplus length absorbing mechanism 70 that absorbs the surplus length portion.

  The flat electric wire W has a connector C1 on one end side connected to a connector (not shown) on the vehicle body 1 side and a connector C2 on the other end side connected to a connector on the sunroof side (not shown). The flat electric wire W is a flexible flat cable. In the flat electric wire W, the outer periphery of the insulating layer is further covered with a protective layer (not shown).

  As shown in detail in FIG. 11, the surplus length absorbing mechanism 70 is slidably disposed on one rail member 11, similarly to the sliders 21, 23, and 25. The slide structure will be described below.

  The surplus length absorbing mechanism 70 includes a case 71, a rotating body 80 accommodated in the case 71, and a spiral spring 90 that is an urging means accommodated in the case 71.

  The case 71 has a substantially cylindrical shape with both side surfaces closed, and is composed of two divided case bodies 72 and 73 assembled to each other. The divided case bodies 72 and 73 have a wire winding case portion 74 and a pair of sliding portions 75. A first electric wire port 76 is provided on the outer peripheral wall of the electric wire winding case portion 74 of the split case body 72. A second electric wire port 77 is provided in the sliding portion 75 of the split case body 72. The first electric wire port 76 is disposed at a position higher than the sliding portion 75, and the second electric wire port 77 is disposed at the same height as the sliding portion 75.

  As shown in detail in FIG. 9, the pair of sliding portions 75 are respectively disposed in the pair of slide guide paths 12 of the rail member 11. The sliding portion 75 has a sliding projection 75 a extending along the longitudinal direction of the rail member 11. The upper and lower inner surfaces of the slide guide path 12 are in contact with the upper and lower sliding projections 75a. Therefore, the surplus length absorbing mechanism 70 slides in line contact with the rail member 11. Since the contact area is thus small, the extra length absorption mechanism 70 has a small sliding resistance with the rail member 11.

  The rotating body 80 is formed of an integral member. The rotating body 80 includes a circumferential rotation guide circumferential wall 81 that is slightly smaller than the inner circumferential diameter of the split case body 72, and a wire winding provided at a position shifted in the axial direction with respect to the rotation guide circumferential wall 81. And a side wall 83 connecting the rotary guide circumferential wall 81 and the wire winding portion 82. The rotating body 80 is rotatably accommodated in the case 71 (the divided case bodies 72 and 73) by the rotation guide circumferential wall 85 being guided by the inner peripheral wall of the divided case body 72.

  The wire winding part 82 has a slit 84 that passes through the center of rotation of the wire winding part 82. The slit 84 opens at a position facing the wire winding portion 82 at 180 degrees.

  The flat electric wire W is inserted into the slit 84 at an intermediate position in the length direction, and is fixed to the rotating body 80 here. The flat electric wire W guided to the outer periphery of the wire winding portion 82 from one opening of the slit 84 is drawn out of the case from the first wire port 76 in a state where it can be wound around the wire winding portion 82. The flat electric wire W drawn out of the case from the first electric wire port 76 is connected to the movable body (sunroof) side where the connector C2 at one end is one side.

  The flat wire W guided to the outer periphery of the wire winding portion 82 from the other opening of the slit 84 is drawn out of the case from the second wire port 77 in a state where it can be wound around the wire winding portion 82. The flat electric wire W drawn out of the case from the second electric wire port 77 has a connector C1 at the end thereof connected to the vehicle body 1 (fixed portion) side.

  The spiral spring 90 is disposed in the inner circumferential space of the rotation guide circumferential wall 81. The spiral spring 90 has an outer peripheral end 90 a hooked to the rotating body 80 and an inner peripheral end 90 b hooked to the case 71. The spiral spring 90 rotates the rotating body 80 in a direction (R arrow direction in FIGS. 10A and 10B) that winds both the flat electric wires W on the sunroof (movable body) 30 side and the vehicle body (fixed portion) 1 side. Is energized.

  In the above configuration, when the actuator 49 is driven, the pair of drive belts 40 moves so that one end thereof is at the same position in the vehicle front-rear direction FR, and the sunroof 30 is shifted to the positions of the three patterns as shown in FIG. Can do.

  When the sunroof 30 moves in a direction away from the surplus length absorption mechanism 70 (in the direction of arrow B in FIG. 11B), the rotating body 80 rotates against the spring force of the spiral spring 90, and Pulling out the wound flat electric wire W on the sunroof 30 side and the flat electric wire W on the vehicle body 1 side (states of FIG. 10 (a) to FIG. 10 (b), FIG. 10 (b) to FIG. 10 (c)), The surplus length absorbing mechanism 70 moves the rail member 11 toward the sunroof 30 side. The surplus length absorbing mechanism 70 moves at half the speed of the sunroof 30 while pulling out the same length of the flat wire W on the sunroof 30 side and the flat wire W on the vehicle body 1 side.

  When the sunroof 30 moves in a direction approaching the surplus length absorbing mechanism 70 (A arrow direction in FIG. 11A), the rotating body 80 is rotated by the spring force of the spiral spring 90, and the sunroof 30 in FIGS. As indicated by the arrow D, the flat wire W on the sunroof 30 side and the flat wire W on the vehicle body 1 side are both wound around the wire take-up portion 82 (FIG. 10 (c) to FIG. 10 (b), FIG. 10 (b). ) To the state shown in FIG. 10A), the extra length absorbing mechanism 70 moves the rail member 11 in a direction to move away from the sunroof 30 side. Thereby, the surplus length is absorbed. The surplus length absorbing mechanism 70 moves at half the speed of the sunroof 30 while winding the flat wire W on the sunroof 30 side and the flat wire W on the vehicle body 1 side by the same amount.

  In this manner, in the transition of the three-pattern sunroof 30, power is always supplied to the sunroof 30 from the power source on the vehicle body 1 side via the flat electric wire W.

  As described above, the rail member 11 fixed to the vehicle body 1 side which is the fixed portion, the sliders 21, 23, 25 moving along the rail member 11, and the movable body supported by the sliders 21, 23, 25. A movable body feeding structure that feeds power from the vehicle body 1 to the sunroof 30. The movable body feeding structure includes a flat wire W and a surplus length absorbing mechanism 70 that winds up a surplus portion of the flat wire W. The absorption mechanism 70 is movably disposed along the rail member 11, and the surplus length absorption mechanism 70 is an electric wire winding unit that winds up both the flat electric wire W on the sunroof 30 side and the flat electric wire W on the vehicle body 1 side. A rotating body 80, and a spiral bar which is an urging means for urging the rotating body 80 in the winding direction together with the flat electric wire W on the sunroof 30 side and the flat electric wire W on the vehicle body 1 side. And a 90. Because of such a configuration, the surplus length absorbing mechanism 70 may be attached to the rail member 11 on which the sliders 21, 23, and 25 move, and it is not necessary to separately install a rail member for the surplus length absorbing mechanism 70. Easy to install. The surplus length absorbing mechanism 70 is provided with a rotating body 80 that winds up the flat electric wire W and a spiral spring 90 that is an urging means for urging the rotating body 80, both of which are arranged around the center of rotation. Therefore, the structure is simple. As described above, it is possible to provide a power feeding structure for a movable body that is easy to mount and can be configured compactly.

  A flat electric wire W on the sunroof 30 side and a flat electric wire W on the vehicle body 1 side are fixed to the electric wire winding portion 82 at a position opposed to each other by 180 degrees. Therefore, although the tension from the flat wire W on the sunroof 30 side and the tension from the flat wire W on the vehicle body 1 side act on the wire winding portion 82, the two tensions do not act as an unbalanced load.

  The flat electric wire W is routed along the rail member 11, and the surplus length absorbing mechanism 70 is disposed at the end of the rail member 11 in the direction in which the sliders 21, 23, 25 move. Therefore, the space of the rail member 11 in which the sliders 21, 23, and 25 are moved can be used as the routing space for the flat wire W, and it is not necessary to separately secure a space for routing the flat wire W.

(Modified examples of sliding parts)
FIG. 12A shows a sliding portion 75A of the first modification. 75 A of sliding parts of a 1st modification are leaf spring shape, and are contacting the upper and lower inner surfaces of the rail member 11 with a spring force.

  FIG. 12B shows a sliding portion 75B of the second modified example. The sliding part 75B of the second modification is a rotating body and moves along the rail member 11 while rotating.

  FIG. 13A shows a first electric wire port 76 and a second electric wire port 77 of the first modification. The first electric wire port 76 and the second electric wire port 77 of the first modification are arranged at the same height position with respect to the sliding portion 75. More specifically, the first electric wire port 76 and the second electric wire port 77 are arranged at the height position of the rotation center of the rotating body 80.

  An external force from the flat electric wire W on the sunroof 30 side and an external force from the flat electric wire W on the vehicle body 1 side act on the case 71, but the rotational force due to the two external forces is offset, so the case 71 has a rotational force. Does not work. Thereby, the surplus length absorption mechanism 70 slides smoothly.

  FIG. 13B shows a first electric wire port 76 and a second electric wire port 77 of the second modification. The 1st electric wire port 76 and the 2nd electric wire port 77 of a 2nd modification are arrange | positioned in the same height position with respect to the sliding part 75 similarly to the 1st modification. However, unlike the first modification, the first electric wire port 76 and the second electric wire port 77 are arranged at the same height as the sliding portion 75.

  Also in the second modified example, the rotational force due to the two external forces is canceled as in the first modified example, and thus the rotational force does not act on the case 71. In addition, when the two external forces have different magnitudes for some reason, the case 71 does not act as a large rotational force.

  FIG. 14 shows a modification of the slit 84 of the wire winding portion 82. In the slit 84 of this modification, two opening positions are formed at a 90-degree rotation position. The two opening positions of the slit 84 may be any position or the same position. However, as described in the above-described embodiment, if the position is 180 degrees, the tension from the flat wire W on the sunroof 30 side and the tension from the flat wire W on the vehicle body 1 side are biased with respect to the wire winding portion 82. Does not act as a load.

  FIGS. 15A and 15B show the first electric wire port 76 (and / or the second electric wire port 77) of the modification. A tip portion of the first electric wire port 76 of the modified example is formed in the tapered portion 78. A wiping member (sponge material) 79 is disposed in the first electric wire port 76. The flat electric wire W is wound into the case 71 of the surplus length absorbing mechanism 70 while sliding on the tapered portion 78 and the wiping member 79. Water, dust or the like adhering to the flat electric wire W is wiped off by the tapered portion 78 and wiped off by the wiping member 79. In this way, it is possible to prevent (waterproof / dustproof) water, dust and the like attached to the flat electric wire W from entering the case 71.

(Application examples of the present invention)
In the above embodiment, the sunroof 30 has a light control panel and supplies power to the light control panel. However, in order to prevent the sunroof 30 from being caught, the sunroof 30 is provided with a touch sensor, and power is supplied to the touch sensor. In this case, the present invention can be applied. When the touch sensor detects an object or the like, control is performed to reverse the drive motor of the sunroof 30. As a power supply target on the movable body side, illumination (LED illumination) mounted on the sunroof 30 is also conceivable.

  In the above-described embodiment, the movable body is the sunroof 30 and the power feeding structure to the sunroof 30 has been described. However, the movable body can be applied to a power feeding structure to a movable body that moves relative to the vehicle body 1, such as a sunshade, a side glass, and a sheet. Further, the present invention can be applied to a power feeding structure to a movable body other than the vehicle.

  In the said embodiment, since the electric wire is the flat electric wire W, winding and formation of a spiral form are easy. However, the electric wire may be a cable having a round cross section regardless of its form.

  In the embodiment, the extra length absorption mechanism 70 has the rotation axis direction in the horizontal direction and the flat surface of the flat electric wire W is drawn out in the horizontal direction (lateral direction). The flat surface may be pulled out in a vertical direction (vertical direction), or in other directions.

  In the case where a solar panel is employed instead of the movable glass, the present invention can also be used for power feeding from the solar panel (movable body) to the vehicle body 1 side.
